1.1 PRESENTATION
Multi Power 184 is an inverter DC TIG/MMA portable welding power source.
The sturdiness of the components of this unit makes it a reliable working companion for workshop and
outdoor applications.
The available DC TIG functions and digital control make this unit ideal for maintenance, building con-
struction, and light metalwork.
In MMA welding the Hot Start and Arc Force functions are adjustable and they allow improved arc strik-
ing, a atter bead and more uniform weld.
The Anti Sticking function makes it possible to detach the electrode rapidly from the workpiece in the
event of accidental sticking.
Up to 4,00mm diameter electrode welding is possible in MMA.
The power source is designed to guarantee safety and exibility through the following features:
OVERCUT: in case of over-voltage in the supply line, the supply to the power source is cut o.
The overcut protection protects electronic parts of the machine against damage caused by voltage
surges.
CURRENT AUTO-CALIBRATION: the power source works at a supply voltage ranging between
115V~±15%/50-60Hz and 230V~±15%/50-60Hz.
The maximum value of the adjustable welding current is automatically limited based on the supply volt-
age measured when the power source is switched on.
DERATING: Derating limits current during welding when supply voltage drops below the limit value of
190Vac.
This limits current input so as not to overload the inverter and keeps the welding arc stable.
FANS: Fan speed varies based on power source internal temperature measured by thermal sensors.
This function brings the following improvements:
- reduction of noise.
- reduction of dust extracted (cleaner equipment, less maintenance).
The welding modes and procedures available are those indicated in the table.

2.4 PREPARING FOR MMA WELDING
1. Set the welding power source ON/OFF switch to “O” (unit o).
2. Plug the power cable plug into a mains socket.
3. Choose the electrode based on the type of material and thickness of the workpiece to be welded.
4. Insert the electrode in the electrode holder.
5. Connect the electrode holder clamp plug to the following welding socket: Positive pole welding
socket.
6. Connect the earth clamp plug to the following welding socket: Negative pole welding socket.
7. Connect the earth clamp to the workpiece being processed.
DANGER!
Electric shock hazard!
Read the warnings highlighted by the following symbols in the “General prescriptions for use”.
8. Set the welding power source ON/OFF switch to “I” (unit on).
9. Select the following welding mode on the user interface: MMA
10. Set the required welding parameter values on the user interface.
When the remote control [RC] is connected and enabled, the welding current can be adjusted.
The system is ready to start welding.
